This invention relates to the art of dump cars and is more particularlyconcerned with a novel'. construction of ya lcar designed for dumpingmovement-'in'two directions.

f A dump car madein-jaccordancewith this invention `comprises generallyfacar frame which ismounted on the lwheelftrucls and which operativelysupports the dumping body. An important object in View is theprovisionof a car -frame which is characterized constitutes theso called backboneofthe frame., Inasmuchy as the fframe necessarily accommodates dumpingaction onthe partof the dumpingzbody itis importanttolocate a structureaffording the main rigideects cenf trallyand'longitudinally of thelcarwhere it ment. i

"More in detail, this invention contemplates a car framejconstruction'having upper and lower. endsills at,y each end ofthecarwithy i vboth the end'sills at one endconnected to both the end'sillsat the other end by the center sill. The upper endsillsfconstitute atrackway on which the car. body operates while dumping", while-the lowerendl sills yarefconnected :by side ysills which aredisposed beneath thelevel `ofthe'center sillvat whichV locationfthey do not interferewiththe tilting movement. Another important feature of they presentinvention is associated jwiththe mounting of latchfmeans for maintaining`the dumping body in normalposition and which ylatch means is operableto permit fof; dumping movement; In vaccordance with this Vinventiona'pair ofy latch members yare pivotally mounted' at oneend of a pairKAofinteritting plates that are Icarried in offset relation 1, by thebody end walls.

The car frame yA .includes plural: endfsilll .A

constructions at each end of-thecar'which are substantiallyv duplicatesf and which are connected by a center sill-'10. 'IKhe'fendrsilllpris'ing an upper end sill and rocker support c 11`and a lowerend sill12 which is shorter than the upper end silland has its center linecoincident with thev upper end 'sill 11. LThe `center sill '10 isof Ibeam: formation and 'aiixed to the ends thereof onieach side of lthewebportion are a pair of angle-bracketshavinglegs 13 and 14rivetedrespectivelyto the centerfsill and upper end sill 11, whichlatter is of channel formation. i

Supplemental: angle bracketsv15-arelsimiv larly securedA to the centersill `10 and lower sill y12; alsofof chan'neliformatiomxandiclips 65 "10tothe end vsills .12, 4to yrigidly connect the f f;

connectithe ,lower flange of ythecentersill respectiveparts." f Thelower 4end sills `12 "at eachend of the car areconnected at theire`xtremities byrolled'channelsidesills 16. The

umv

V is connectedwithtside sill 16 jas by rivets and this leg 19terminate'sasli'ght distance (above the side sill 16 as shown in Fig. 4. Gussets 66are also provided to reinforce the ineinbers 12 and 16 at the fourcorners of the -un- 15 deri'rame, as shown in Fig. 3.

The lower end sill 12 carries draft means for the car in the form of acoupling designat-ed 2O which is anchored 'to the end sill 12 asshoWna-t 211. The upper end sill ,11 carries latch-engaging pins 22which are braced by brackets 23 having oiset portions 24 connected withthe Vinain ybody portion of the jbrackets by an inclined intermediateportion 25. per end sill 11 by Ariveting land the oilsets 24 areapertured to receiveV the;yp'ins l22, As above notedthe 'end sill 11 isofcha-nnel vformation and the upper iiange v'thereof designated l26 is,provid-ed with a series ofequidistantlyspaced openings 27 for Vapurposek to be la-ter specified. i

Trucks B are connected to the frame A by the angle plates28,the'angularlegs `of which are aziixed ;to the journal boxes of the`trucks and rthesside sills 16 respectively. :Brac'ing means `at themiddle of the car frame is provided in the form Vof a tie plate 29 whichis attached-to the side sills and center sill Vrespectively lbysufitable rivet connection. i 10 Dumping 'body' C is yci' general boxformation and comprises a floor 31whic`h may be'oaf plank-,endWalls-32and-sides den'ed by swingdoors 33. The latter may include asheet metal wall 34 :that is braced against bending 15 hy sti'ieningmeans inthe form Iof angle bars 35.. The planking ofthe floor `31-may befaced with vsheet metal plates `6() andy-61 on the top and bottom faces.The doors `33 are pivotally mounted `at the t'op of the `end walls y5032 as indicatedat 36 and door lock mecha- 'nism for maintaining thedoors in closed@ osi'tion and Ifor permitting of thei'r swinging isassociated with the lower edge of the door and the side edge of thefloor 3l. This door 'H5 Tlock mechanism is shown at 37' and may be oftheconventional type. i

The structure which rockably supports the body C on the tram'e Acomprises rocker trames 38,one being lat'tacl'ied to each of the endWal=ls2 32y Oneof the rocker frames consists o-fa -U-`slfrapedcastinghaving a flange 39 parallely with and riveted to the endwall andfaeurvedilange140 Ialt right angles thereto.

` This angular casting -Iis reinforced by -ribsi41 05 which areintegralwith the respective flanges.

Brackets 23 are anchored tothe up-V A cross piece 42 connects the legsof the U and this cross piece, together with the lange 39, is anchoredto end wall 320i the body C.

The flange of the rocker frame 38 is provided at the bend of the U withteeth 43 that are complementary to the openi s 27 in theendsillfflangeQ. Y Senseo! these 4celda-43 are at all times received inthe openings 27 and functionto prevent lateral displacement of aie-badlyc Twist respect to une frame A. Y T0 the end or incitingr'ekinginovjement ofthe body C chains 44 are provrded'atbach "side ofthe'car and these chains 44 have their `ends afliXed to Athe .body C andthe frame A respectively as 'shovv'n rat 45 and 46.

A Pivotal mountings -for thelatch :members 47 are provided 'in the ,formof 43 which are carried :by the end Vwalls 32 -andfoifsets 49 and 50 ofinter-fitting brackets-51nd 52,which are suitably y mounted 'onf ntheend wal-Is `532'. 'lhe oil'set 50 has a. flange 53 rthat is connected tothe inclined iportion -54 of the-bracketl as by riveting toprovide arigid structure. The pins `48 4extend through apertures inthe latchmembers 47 vvh-i-lewthe 4other extremities ofthe latch mem-bers arerecessed as show-n Vat 55 to provide hooks 4for engagement with the pins22. In operation the teeth 43 are received Ain openings?? when the c'aris an Vupright or normal position in which dumping is prevented yby thehooks of therlatch vifnge'rn'lfier-s 47 engaging `the pins 22fgtomaintain thisnon'- discharging position. When the car is to :be dumpedthe `door33 -isreleased-by proper operation of the rdoor lock 37adiacent the side on which the contents fare to befdnmped, and thelatch'iniember 47 lon thesideopposi-te that on which the contents are bedumped is swung free of the pinsf22. Under-these con'- ditionsgravityVaction will have to be supplemented lonly very slightly to cause thebody C to tilt on ythe-rocker frames. As the Abody rocks the door 37swingsopen and the cointents anedisdaarged. It is notable Ythat thechains j44 are effective to -li'mfit the extent of thejtilti'ngmovemeilt-V While a preerredspeciiic embodlment is hereinbefore 'setforth it is understood that I `am not to be limited to the exactconstrue tion illustrated "and described because various modicationsofthesedetilsfnray be provided in `pitting the invention practice Withinthe purvliewfof the appended claims;
